Hey guys. Im having a little problem here in choosing which is better to use with my Serostim kits (18 IU's per vial).
The more i read on it the more confused i get, and the last thing i want to do is do it the wrong way and it go to waste.

Im doing about 3-4 IU's a day, and each vial is lasting me around 6 days. I then take one off.

Could someone who "KNOWS" please finalize this only worry i have?

I want to know what is better to use with them. The Sterile water that came with it, or order Bac water?

Thanks in advance, Fina.
